Effects of noninvasive ventilation on lung hyperinflation in stable hypercapnic COPD.
Two previous uncontrolled studies have suggested that noninvasive mechanical ventilation (NIMV) in patients with hypercapnic chronic obstructive pulmonary disease (COPD) improves arterial blood gas tensions by decreasing lung hyperinflation with the consequent reduction in inspiratory loads and changes in ventilatory pattern. The aim of this randomised placebo-controlled study was to determine ...
متن کاملPhysiological effects of posture on mask ventilation in awake stable chronic hypercapnic COPD patients.
Stable chronic hypercapnic patients are often prescribed long-term mask noninvasive pressure support ventilation (NPSV). There is a lack of information on the effects of posture on NPSV. Therefore posture induced changes in physiological effects of NPSV in awake stable chronic hypercapnic patients were evaluated. In 12 awake chronic obstructive pulmonary disease (COPD) patients breathing patter...
متن کاملThe effects of long-term noninvasive ventilation in hypercapnic COPD patients: a randomized controlled pilot study
INTRODUCTION Noninvasive ventilation (NIV) is a well-established treatment for acute-on- chronic respiratory failure in hypercapnic COPD patients. Less is known about the effects of a long-term treatment with NIV in hypercapnic COPD patients and about the factors that may predict response in terms of improved oxygenation and lowered CO(2) retention. METHODS In this study, we randomized 15 pat...
متن کاملPhysiological and clinical effects of diurnal noninvasive ventilation in hypercapnic COPD.
To assess the clinical impact of noninvasive mechanical ventilation (NIMV) on stable hypercapnic chronic obstructive pulmonary disease, changes in exercise capacity, dyspnoea and simple physiological parameters were evaluated. The time course of these effects during treatment and recovery was also assessed. Patients were randomly allocated to NIMV (n=27) or sham-NIMV (n=15), applied 3 h.day-1, ...
متن کاملCPAP decreases lung hyperinflation in patients with stable COPD.
BACKGROUND Dynamic hyperinflation, caused by expiratory flow limitation, markedly increases resting end-expiratory lung volume (functional residual capacity) in many COPD patients. OBJECTIVE To determine the impact and duration of impact of CPAP on hyperinflation and airway resistance in patients with stable COPD. METHODS In a case series, 21 patients underwent CPAP at 8 cm H(2)O for 15 min...
